Hey, turns out this "Google" craze might be here to stay.

The challenge for Google in the past few quarters has been convincing marketers to pay as much for mobile ads as they do for desktop ads, a task that's become increasingly pressing as Web usage shifts to smartphones.

Part of the way Google is addressing this issue is through the "enhanced campaign" strategy it introduced last year, which requires advertisers to buy across multiple platforms.

Google said marketers paid 6% less per ad in the second quarter compared with last year, but ad viewing rose 25%, giving the company strong revenue growth. Google held a whopping 68% share of the U.S. search market as of May, according to comScore.
